Notes on Nonlinear Fracture Mechanics
Sat, 2007-01-27 14:03 -John W. Hutchinson
These are the notes I wrote at the Technical University of Denmark in 1979. Zhigang Suo and I will be using these in thecourse on fracture and thin film mechanics(ES 242r) this spring (2007). This is a joint course with the University of Nebraska.

This is great!
One question I am frequently encountered is: how do we analyze fracture with large scale plastic deformation, theoretically and numerically? I learnt a little from Zhigang's class on HRR solution, Dugdale-Barenbllat's cohesive mode, etc. It seems not enough to solve any practical problems. I will try to learn more from this notes. Thank you, John!

我同意瑞。
我同意瑞。大规模的问题是explained very nicely in this lecture note. Despite the current research activities on small-scale plasticity mechanisms, many materials scientists are still inclined to understand it from continuum mechanics.

I second RH! I am currently a TA for Fracture Mechanics (at University of Washington, Seattle) and this is a wonderful resource. :) Thank you John!
John's Notes with Pages Rotated
These are indeed a great resource. I have used them many times.
For those who would like to read John's notes on their computers, there is a copy posted inmy blogwith the pages rotated counterclockwise by 90 degrees.
Dear Dr.
Dear
Dr. Hutchinson,
The
fracture energy can be calculated experimentally from the area under P-w curve divided
by ligament length. This was calculated by many researchers by taking w at the
crack mouth; however, according to my understanding, from the definition of
fracture energy, w should be calculated at the crack tip.
I
would appreciate if you could help me in this regards
Thank you
